Ying-ti 10Pcs Aquarium Filter Cartridge for Aqua-Tech 10-20 Power Filters

Just as good as name brand style filters. The material and construction are effectively identical, and they work exactly as you would expect in a 10-20 power filter. You can get about 30-60 days of use with these depending on your tank conditions, and maybe more time with gentle washing at a sink. These fit snugly in the pump, dont rattle or shift, and are easy to rinse off or just toss in the recycling bin when they are done drying out.

Exactly as described fits my filter perfectly, I couldn’t be more happier and an exceptional great prize thank you I will be using you as a vendor in the near future. Thanks again. Hope this is helpful to anyone that is looking to find a great filter at a great price fast delivery.

These aquarium filters keep the water clean and clear. Easy to install and fit perfectly. My fishes seem happier and the tank stays fresh longer — definitely recommend!

The filters work as designed and provide filtration to my 20 gallon fish tank as expected. Keep my water in the tank clean and clear and usually I changed it out every month. The carbon pieces in the filter is a little less than I expected, but for the price, I guess it is acceptable. Will buy again when the existing ones are used up.

Great price and many for replacement. Fit on my air machine.

Fits perfectly and way cheaper than the store bought ones.

Amazon can’t ever get my product here on time the product I bought is fine. The fact that they can’t seem to deliver when they say they will is not fine.

good value

They turned the water yellowish brown.
